SPIDERS OF THE ORB- WE AVER GENUS PARAWlXiA IN
AMERICA (ARANEAE: ARANEIDAE)
HERBERT W. LEVM
Abstract. Parawixia are Neotropical, nocturnal orb
weavers related to Acanthepeira, Eriophora, Wag-
neriana, and Wixia. The relationship is based mainly
on synapomorphie character states of inale and fe-
male genitalia.
Of the 26 species of Parawixia found in collections,
10 are new, four are known only from males, six from
females. There are 24 new synonyms of species and
subspecies naiives, Most Parawixia species are found
in the Amazon area primarily, and in Central Amer-
ica and eastern Brazil Many species probably build
webs in the canopy. The social nianduti spider {Para-
wixia InstriafaX which made such an impression on
Darwin, belongs to Parawixia.
INTRODUCTION
Among the" interesting spiders found in
South America by Charles Darwin, as re-
ported in 1839 in The Voyage of the Bea-
gle, was a social orb- weaver species. *'. , .
1 found near St. Fe Bajada [present day
Parana] many large black spiders, with
ruby -coloured marks on their backs, hav-
ing gregarious habits. The webs were
placed vertically, as is invariably the case
with the genus Epeira: they were separat-
ed from each other by a space of about
two feet, but were all attached to certain
common lines ^ which were of great length,
and extended to all parts of the commu-
nity. In this manner the tops of some large
bushes were encompassed by the united
nets. Azara [F. de Azara, 1809, Voyage
dans rAmeriqiie meridionale] has de-
scribed a gregarious spider in Paraguay,
which Walckenaer thinks must be a The-
ridion, but probably it is an Epeira, and
perhaps even the same species with mine,
I cannot, however, recollect seeing a cen-

versity, Cambridge, Massachusetts 02138,
tral nest as large as a hat, in which, during
autumn, when the spiders die, Azara says
the eggs are deposited. As all the spiders
which I saw were of the same size, they
must have been nearly of the same age.
This gregarious habit, in so typical a genus
as Epeira, among insects, which are so
bloodthirsty and solitary that even the two
sexes attack each other, is a very singular
fact/'
It is a reflection on the current status of
spider studies that this spider, though
named bistriata in 1836 by the Swiss trav-
eler Rengger, and frequently mentioned
(Busk irk, 1981), has never been illustrated
before. In 1932 Mello-Leitao placed hist fi-
at a in Eriophora and was followed by the
catalogers Roewer and Bonnet. Mello-Lei-
tao did not provide illustrations and on
receiving some specimens 15 years later
did not recognize them and gave them a
new name. Only recently Shear (1970)
considered that Darwin's spider may have
been a Cyrtophoray an orb- weaver genus
with some social species. Several investi-
gators (Fowler and Diehl, 1978; Fowler
and Gobbi, 1988a,b) studied the behavior
but were uncertain as to whether there are
one or two species that are social. Radcock
(1932) realized that a species described and
illustrated previously by TuUgren from
Bolivia was a social spider also found in
Paraguay as reported by Carter (1928), the
collector of Badcock's specimens.
This paper is part of the ongoing study
of Neotropical orb weavers (Herman and
Levi, 1971; Harrod, Levi, and Leiben-
sperger, 1991; Levi, 1968, 1971, 1985, 1986,
1988, 1989, 1991a,b). The primary pur-
pose of my revisions is to help determine

species within a given genus, in this case
Parawixia. Such determinations are need-
ed because spider species are often of eco-
nomic importance or biological interest
(e-g., Parawixia histriata), A secondary
function is to provide information aiding
in the understanding of evolutionary re-
lationships within the genus. Sequestering
this information may be easy in small fam-
ilies but is much more difficult in large
and diverse families. Studies on the evo-
lution of small families less diverse than
the orb weavers have been published based
on an understanding of a few species in
the genus (Coddington, 1986).
Before a genus has been revised, it may
only be known by its most common species
or by the type species to w hich the generic
name is attached. However, the type spe-
cies is often the most aberrant member of
the genus, and has been placed in its own
genus specifically because of unusual char-
acters that may not occur in more "aver*
age ' congenerics. Also, in large diverse
families, the study of all species is neces-
sary to determine generic-level characters.
To take examples, when 1 first worked
on Eriopliora in 1970, 1 assumed that Para-
wixia V>elonged to the same genus perhaps
as a species group of Eriophora. Careful
study of Parawixia showed this assumption
to be erroneous because^ several characters
were found to be apomorphies for Para-
wixia only (see below). In another study,
1 characterized the genus Wixia as lacking
a long scape (Levi, unpublished key). I
have since found that this absence is only
true for Xearctic species; many Neotrop-
ical species (which otherwise share apo-
murphies with Nearctic Wixia and can
fairly be cons itle red congeneric) do have
a long scape (Levi, in prep,). These char-
acters wert* not elucidated until revisions
of the genera in question hud been done*
Fvohitionary analyses of generic rela-
tionships cannot be made until tlie relevant
genera themselves have bt m revised and
the limits of the individual genera defined.
Any premature analysis would have to be
revised with each successive generic re-
vision. 1 am currently completing work on
a sub-group of the family Araneidae, char-
acterized by the presence of a palpal para-
median apophysis and including the gen*
era Parawixia, Eriophora, Acanthepeira,
Wagneriana, Alpaida, Wixia, Acacesia,
and Cijclosa. When the final members of
this group, Wixia and Acacesia (both
manuscripts in preparation), are revised,
comparison and evolutionary analysis of
this group w ill be possible,
METHODS AND MATERIALS
The methods used are the same ones as
those used in previous papers on Neotrop-
ical orb weavers. Relative eye sizes were
measured by comparing their diameter in
profile with that of the anterior median
eyes. The distance separating the eyes of
the anterior row^ was measured relative to
the diameter of the anterior median eyes
in profile; and that the posterior row to the
diameter of the posterior median eyes, A
forthcoming paper on the genus Wixia w ill
describe these methods in some detail.
The specimens used came from the fol-
low in g collections,

Parawixia F. P.-Cambridge
Parawixia F. P. -Cambridge, 1904; 487, Type species
by original designation Epeira de strict a O. P.-
Cambridge, 1889.
Diagnosis, Parawixia can be distin-
guished by the epigynum which, unhke
that of Wagneriana, has a scape as long
as or longer than the width of the base
and, unlike that of Eriophora, has the scape
originating from the posterior margin of
the base (Figs. 9, 19, 74). The distal end
of the paramedian apophysis in Parawixia
males is in the shape of a disk with a finger
along the distal margin and extending be-
yond it (Figs. 7, 26, 39). In Wagiwriana
the paramedian apophysis is L-shaped; in
Wixia and Acacesia the paramedian
apophysis is a straight prong. Tn Acanihe-
peira and Eriophora the paramedian
apophysis is a separate sclerite. Unlike that
of Eriophora, the palpal patella of Para-
wixia males has only one macroseta.
Coloration, lateral eyes, and abdomen
shape are distinctive. There are dark marks
between median and lateral eyes (Figs. S,
4, 12), paired dark spots on the carapace
(Figs. 24, 62), and a pattern of paired light
patches on the sternum (Fig. 6). In some
species, these marks are missing. The lat-
eral eyes are on the sides below tubercles
(Figs, 2-5), The spherical to trapezoidal
abdomen has 2 to 6 pairs of lateral tuber-
cles and xisually 2 to 3 tubercles in a me-
dian line posteriorly (Figs. 12, 17).
In collections from Mexico and Guat(^-
mala, where the ranges of the two genera
overlap, females of Parawixia can be sep-
arated from those of Nearctic Acanthe-
peira (Levi, 1976; fig. 12) that also have
paired spots on the carapace, but have an
abdominal median anterior tubercle lack-
ing in Parawixia (Figs. 12, 17, 49).
The shape of the embolus of the male
palpus and its attachment (soft, lightly
sclerotized tissue with a small hematodo-
cha) may be an autapomorphy. The round
to trapezoidal shape of the tubercle-bear-
ing abdomen is an autapomorphy of Para-
wixia species, as are the paired light marks
on the sternum (Fig. 6, Table 1).
Description. Carapace orange to brown
with one or more pairs of spots and char-
acteristic dark marks betw een median and
lateral eves and behind the lateral eyes
(Figs. 12, 17, 37), There are few hairs on
the carapace. Parawixia hist rial a, how-
ever, has a hairy carapace and lacks the
paired spots. Chelicerae of all are darker
distally than proximally. The endite and
labium rnav be dark. The sternum is dark
with pairs of lighter patches (Fig. 6) except
in P. baracoa, F. undulata, and P. bistria-
ta. The coxae are orange to brown w ith
dusky patches and the legs have indistinct
dark rings. The dorsum of the abdomen is
variable in individuals of each species but
the venter has a species-characteristic pat-
tern. It is black w ith a distinctive median
* There are exceptions.
** l\ bistriata and £. nephiloides (Levi, 1971) have a large macroseta and a smaller one on the male palpal
patella.

while patch (Fie. 31). pairs of white marks
(Figs. 18. 44: 14'0.147)Vnther distinctive
markings always different from those of
related species.
The anterior median eyes are the larg-
est, the lateral eyes the smallest. The pos-
terior median eyes ma) be on a shght
swelling in Paratvixia^ but are not in Wag-
neriana, Acanthepeira, or Eriophora. In
Wixia (in prep.) and Acacesia (in prep.)
the posterior median eyes are on a swelling
with tlie eves directed toward the sides.
Parawixia have a subspherical to trap-
ezoidal abdomen with four to 15 tubercles,
three or four pairs on the sides toward the
anterior and middle, one pair posterior on
the sides, and two to three single tubercles
in a posterior median line (Figs. 12, 17),
All individuals of a species have the ab-
domen about the same shape. Adult Para-
wixia hist hat a females lack these tuber-
cles, but im matures and males frequently
have three lateral pairs and a faint pos-
terior median tubercle (Fig. 157), Only
rarely (in immature and some adult female
P. audax) does Parawixia have a median
anterior tubercle as in Acanthepeira.
Male coloration is as in females. In males
the cephalic region is narrow (Figs. 3, 4)
as in males of EriopJiora and Wagneriana.
It is not narrow in males of Acanthepeira.
The abdomen is the same shape as in the
female but smaller (Fig. 62). The palpal
patella has only one macroseta, except in
F, bisiriata, which has a second smaller,
white mac^roseta. The endite has a tootli
facing a tubercle on thc^ proximal end of
llic palpal ienuir (Figs. 4, 6). There is al-
ways a hook on the distal margin of the
first coxa (Fig. 6) fitting into a groove on
the second femur. The fourth and some-
times third coxae and trochanters of Par-
awixia males (except in F. audax. P. un-
dulata, and P. hist r lata) have one or more
macrosetae (Fig. 6), as in males of Wag-
neriana, Eriophora, Acanthepeira^ and
Wixifl. The second til>ia is armed with
macrosetae and thicker than the first tibia.
As in related genera, the palpus has a para-
median apophysis. The base of the median
apophysis, just above the radix, is usually
modified to resemble a depressed oval w ith
teeth or keels along its margin (Figs. 7, 26,
142, 149, 156), a synapomorphy shared
with Eriophora and important for sepa-
rating species of Parawixia. In Wagner-
iana and Wixia the base is sclerotized,
sometimes with a tooth; in other genera it
usually is not modified or sclerotized. The
embolus is cone- or bullet-shaped (Fig. 7)
in all but P\ kochi. In Eriophora it is of
various shapes. The terminal apophysis of
the Parawixia palpus is partly fused to the
embolus, as in Wagneriana and Erioph-
ora. {Acanthepeira lacks a terminal
apophysis.) This fusion is probably a ple-
siomorphy.
Variation. The dorsal abdominal pat-
tern and coloration differ among individ-
uals of the same species. The number of
macrosetae on the third and fourth tro-
chanters of males is variable and com-
monly differs on left and right sides of the
same specimen.
Relationships. Parawixia is closest to£r-
iophora (Levi, 1971) and Acanthepeira
(Levi, 1976). (he long scape of the epigy-
num is a synapomorphy with Acanthe-
peira and Eriophora species (in Acanthe-
peira the scape is relatively short). Rut in
all Eriophora species the scape originates
from the anterior margin, and folds back
to point posteriorly. The shape of the para-
median aptjphysis of the male palpus
(which is attached to the conductor) and
of the abdomen are autapomorphies for
the genus Parawixia. The tubercles of the
lateral eyes and the pairs of dark spots on
the carapace are synapomorphies with
species of Acanthepeira. The dark streaks
between median and lateral eyes may also
be found in Eriophora edax. The usually
black underside of the abdomen mav have
a median white patch or distinctive pairs
of light or white patches (Figs. 13, IS, 31,
79) that are also found in species of Wixia,
The tubercles on the abdomen are ho-
mologous with those of Wagneriana and

Acanthepeira, therefore synapomorphic.
However, in Wagneriana, the abdomen is
rectangidar, longer than wide and often
with a tail above the spinnerets. Macro-
setae on the third and fourth coxae and
trochanters of males (not always present),
presence of a paramedian apophysis, and
ack of distal hematodocha are synapo-
morphies of these various genera: Para-
wixia, Acanthepeira, Wagneriana, Wixia,
Eriophora, Alpaida, Vcrnicosa, and others
(Table 1),
Natural History, The best known spe-
cies is F. audax y which makes a loose large
web and sits in the hub, cephalic region
down, or in a rolled-leaf retreat, one to
two meters above the ground. Most species
probably live in the canopy and are rarely
collected. Parawixia bistriata is social and
makes webs fairly high up, commonly on
telephone poles. All individuals in a colony
are of the same age and size and during
daytime they cluster together in a shared
retreat (Plate 1; see below).
Note. When working on Eriophora in
1970 1 thought that Parawixia might be a
synonym of Eriophora (Levi, 1971), but
this is not the case (see above). The two
genera are related. No additional species
of Eriophora have been found (only one
doubtful male from Peru),

Note. O. P.-Cambridge (1889) de-
scribed a male and figured a male and a
female, the female of a Wixia. F. P. -Cam-
bridge (1904) illustrated the male with the
correct female and considered the 1889
male, now lost, to be the type and the
correct female a "deuterotvpe." The Brit-
ish Museum has specimens erroneously
marked as types, which come from Gua-
temala, not from the type locality in Pan-
ama. Keyserling (1892) had seen these
Guatemala specimens, which were also ex-
amined by F. P. -Cambridge; the male un-
doubtedly is the same species as the lost
male holotype.
Description. Female from Guatemala.
Carapace orangt thrown, lightest between
median eyes, with paired dark spots and
white setae on cephalic region. Sternum
brown with three pairs of orange patches.
Coxae orange with brown patches; legs
yellowish orange with dark rings and
patches. Dorsum of abdomen light and
dark orange-brown (Fig. 24); venter with
a brow n band and two pairs of w hite spots,
the second pair largest {Fig. 25). Posterior
median eves 0.7 diameter of anterior me-
dians, anterior laterals 0.7 diameter, pos-
terior laterals 0X5 diameter. Anterior me-
dian eyes thtMr diarnt^tcT apart. Posterior
median eyes their diameter apart. Abdo-
men with 11 tubercles; four pairs on sides
and three median posterior (Fig. 24). Total
length 18 mm. Carapace 9.6 mm long, 5.5
wide. First femur 10.6 mm, patella and
tibia 11.7, metatarsus 7.6, tarsus 2.5. Sec-
ond patella and tibia 10.2 mm, third 6.1,
fourth 9.2.
Male from Guatemala. Color as in fe-
male. Posterior median eyes 0.6 diameter
of anterior medians, anterior laterals 0.5
diameter, posterior laterals 0.6 diameter.
Anterior median eyes 0.7 diameter apart.
Posterior median eyes their diameter apart.
Fourth trochanter without macrosetae.
Second femur with ventral row^ of strong
macrosetae, third with a few macrosetae.
Second tibia swollen, thicker than first, with
prolateral macrosetae. Abdomen w ith five
tubercles: a pair anterior and three pos-
terior. Total length 7.5 mm. Carapace 4 J
mm long, 3,4 wide, First femur 4.8 mm,
patella and tibia 6.0, metatarsus 3.5, tarsus
L4. Second patella and tibia 4.7 mm, third
2.7, fourth 4.0.
lUustrations. Figures 19, 21, 23-26 were
made from specimens from Guatemala;
Figures 20, 22, from a female from Chia-
pas.
Note. Males and females were collected
together in Guatemala.
Diagnosis, Females differ from those of
other species by having the greatest width
of the posterior median plate being about
equal to the greatest width of the lateral
plates in posterior view^ of the epigynum
(Figs. 21, 22). Males difter fruui those of
other species by the strongly curved me-
dian apophysis of the palpus (Fig, 26).
Natural History. The Mexican speci-
mens were collected in a cloud forest.

mm, third 2.5, fourth 3.8.
Variation, Total length of females 6.2
to 10.7 mm. The coloration of all four spec-
imens is similar but the Ecuadoran spec-
imen has the posterior median plate less
depressed anteriorly. Figures 27-31 were
made from the holotype.
Diagnosis. This species differs from otli-
ers by having marks on the cephalic re-
gion, lacking marks on the sternum, and
by having only four abdominal tubercles
(Fig. 30). The posterior median plate of
the epigynum (Fig. 28) is diamond -shaped,
unlike that of F. honesta (Fig. 15) and P.
deslricta (Figs. 21, 22).

Description. Female from Depto. Cau-
ca, Colombia, Carapace orange with darker
spots, darker between median and lateral
eyes. Sternum dusky orange with three
pairs of lighter patches. Coxae orange with
darker streaks; legs dark orange w ith dusky
patches and indistinct dusky rings. Dor-
sum of abdomen orange brown (Fig. 37);
venter V)lack w ith a median light spot (Fig.
38). Carapace relatively flat and low. Pos-
terior median eyes 0,9 diameter of anterior
medians, laterals 0.8 diameter, Anterior
median eyes their diameter apart. Poste-
rior median eyes their diameter apart. Ab-
domen with 10 tubercles (Fig. 37). Total
length 1L7 mm. Carapace 4,8 mm long,
3.6 wide. First femur 5.7 mm, patella and

Male from San Pedro, Colombia. Color
as in female with distinct, median white
patch on black venter of abdomen. Pos-
terior median eyes 0.7 diameter of anterior
medians, laterals 0.7 diameter. Anterior
median eyes their diameter apart. Poste-
rior median eyes their diameter apart.
Fourth trochanter with two macrosetae.
Second femur w ith a ventral row of macro-
setae. Abdomen as in female. Total length
8.2 mm. Carapace 4.3 mm long. 3.5 w ide.
First femur 5,1 mm, patc^lla and tibia 6.3,
metatarsus 3.9, tarsus 1.5, Second patella
and tibia 4.9 mm, third 2.9, fourth 4.5.
Note. Males and females have not been
collpcted together but both sexes have been
collected in San Pedro, Colombia, and their
distribution is similar.
Variation. The proportions of the epigy-
nimi of the synt\ pe illustrated are similar
to those of the female from Cauca. In no
two individuals is the posterior median
plate exactly alike (Figs, 33-35), and the
pAnAWixiA^Levi
17
terminal apophysis of males differs slightly
among individuals. Some individuals have
only four tubercles on the abdomen: two
widely separated median anterior tuber-
cles, and two median posterior, close to-
gether. Of the three syntypes of Epeira
rimosa, the epigynum of the one recently
molted is illustrated (Figs. 32, 33, 36), Fig-
ures 36 to 38 were made from a specimen
from Costa Rica; Figure 34 was made from
a specimen from Cauca, Colombia, and
Figure 39, from Magdalena Dept., Colom-
bia. Total length of females 9.7 to 14 mm,
of males 6.2 to 9.5.
Diagnosis. All specimens of this species
have a median white patch on the black
venter of the abdomen (Fig. 38). Females
can be separated from those of P. destricta
and P. barbacoas by the wide posterior
median plate and relatively narrow^ lateral
plates in posterior view of the epigynum
(Figs. 33-35). Males can be distinguished
by the strongly curved median apophysis
and from P. destricta by the shape of the
embolus (Fig. 39),
Natural History. Most specimens come
from high elevations, above 1,000 m, but
a few^ are from low elevations. The pair
from Ecuador came from a rain forest in
Tinalandia.

Note, Males and females were matched
because of similar size and both having
four white spots on the underside of the
abdomen.
Variation. The females other than the
type have three pairs of lateral abdominal
tubercles and five posterior. Total length
of females 11,3 to 15.0 mm. The female
lectotype and the only male have been
illustrated.
Diagnosis. The long, vase-shaped pos-
terior median plate of the epigymim (Fig.

agnostic (Figs. 40, 42), The male differs
from that of P, nesopJiiJa by having four
white spots on the underside of the ab-
doiiien and details of the palpal sclerites.
Natural History. The male was collect-
ed in a cloud forest.

female holotype and a male from Yucatan
have been illustrated.
Diagnosis. Females have a pair of more
or less distinct bulges on the ceplialic re-
gion (Fig. 49). The female can be sepa-
rated from other Central American Para-
wixia species by the relatively long, flat
scape of the epigynum (Figs. 46, 48). In
some individuals the scape has been bro-
ken off. The male can be separated by the
shape of the relatively small terminal
apophysis, the large conductor, and the
shape of the median apophysis (Fig, 51).
This is the only Parawixia species known

diameter. Anterior median eyes 0.9 di-
ameter apart. Posterior median eyes their
diameter apart. Fourth trochanter w ith tw o
short macrosetae. Third femur onlv with
a distinct row^ of ventral macrosetae. Ab-
domen with five tubercles: one pair an-

Note. The male was first thought to be
that of P. barhacoaSy for which only tlie
female is known, but they differ in col-
oration of the carapace, of the sternum,
and of the venter of the abdomen.
Diagnosis. The peculiar shape of the
median apophysis of the palpus (Fig. 52)
distinguisfies the male from males of other
species.

Diagnosis. The first tarsus only, on both
sides, is minute. This may be a character
of the species or a malformation of the
male. The C- shaped embolus, which ap-
pears to have a cap, and the distal lobe of
the median apophysis make the palpus dis-
tinct from that of other species (Fig. 54).

Puuama, were illustrated.
Diagnosis. The abdomen of the females
is trapezoidal (Figs. 59, 62), Females can
be separated from similar species by the
small, square, posterior median plate of
the epigynum (Fig. 57). The palpus of the
male differs from that of any other species
in having a pointed median apophysis
bearing a small knob on its margin (Fig.
61).

Posterior median eyes their diameter apart.
Fourth trochanter with two short macro-
setae. Abdomen with 12 tubercles: the sec-
ond, third, and fourth pairs small. Total
length 8,0 mm. Carapace 4.7 mm long, 8.9
wide. 1 irst femur 6.0 mm, patella and tibia
7.0, nictatarsus 4,2, tarsus 1,4. Second pa-
tella and tibia 5.4 mm, third 3T, fourlli

Note, The male was collected at the type
locality.
Yariation. Total length of females 9,0
t(^ 14,4 mm, of males 8.0 to 8,8, All illus-
trations were made from Barro Colorado
Island specimens.
Diagnosis, The 13 abdominal tubercles,
with anterior laterals double (Fig. 66), and
the narrow^ median posterior plate of the
epigynum, bordered on each side by con-
vex margins of the lateral plates (Fig. 64),
distinguish this species from the Brazilian
P. inopinaia (Fig. 70). The male differs
from F, gnat e male nsis (Fig, 45) and P.
inopinata (Fig. 73) by the shape of the
terminal apophysis and median apophysis
of the palpus (Fig, 68), and from F. gua-
temalensis by having a median w hite patch
on the underside of the abdomen.
Natural History. Parawixia nesophila is
apparently found in forested areas. A male
was found in Costa Rica in leaf litter.

Note. Male and female are matched on
the basis of their similar abdomen shape
(Fig. 72). Also the genitalia of both sexes
(Figs. 69-7 L 73) resemble those of P. ne-
saphila.
Diagnosis. Both the male and the fe-
male are close to the Panamanian P. ne-
sophila. The female differs by having a
bottle-shaped posterior median plate of the
epigynum (Fig. 70). The male differs by
having h>nger prongs of the median
apophysis of the palpus (Fig. 73),

of a folium (Fig. 78); venter dusky with
three to four pairs of indistinct white round
spots (Fig. 79). Posterior median eyes 0,8
diameter of anterior medians, laterals 0.7
diameter. Anterior median eyes their di-
ameter apart. Posterior median eyes tlieir
diameter apart. Abdomen with 15 tuber-
cles: four pairs on sides, one small anterior
median, and six posterior. Of these, one
pair and four medians above spinnerets.

Note, Males and females were collected
together in Mato G rosso, and both were
collected at a second locality in Mato G ros-
so although not together.
Variation. Total length of females 11 to
13.6 mm, of males 6.2 to 9.2, The anterior

ets may be present or absent. Figures 74-
79 \\ ere made from a female from Dia-
mantina, Minas Gerais, Brazil; Figure 80
was made from a male from Meta Dept,,
Colombia,
Diagnosis. Females can be separated
from most Paniwixia species by the shape
of the scape, which has a knob above its
tip. From P. monticola they are separated
by another feature of the epigynum: the
lateral plates overhang the median plate,
forming a slit with almost parallel edges
in posterior view (Figs, 75, 76). The male
can be separated from males of most spe-
cies by the three macrosetae on the fourth
trochanter, by having the median apoph-
ysis distally bilobed, and having proxi-
mallv a small tooth just above the radix
{Fig. 80),

Note. The males were not collected with
females but w ith two males of P. velutina.
Their similarity to females in appearance
and being collected within the same range
suggested the match.
Variation. Total length of females 9.6
to 13.6 mm. The female from Bahia had
the posterior median plate narrower than
the one illustrated (Figs. 82, 83). Females
from Itabapoana and Porto Cabral had the
epigynum with a larger base relative to
tlu* length of the scape. Both females be-
longing to the MNRJ had their scapes bro-
ken off. Figures 81, 82, 85, 86 were made
from the holotype; Figures 83, 84, from a
specimen from Sumarc, Rio de Janeiro, in
AMNH,
Diagnosi.s. In posterior view^ (Figs, 82,
83), the epigynum of P. monticola has a
round posterior median plate, constricted
dorsally, while that of P. veliilina is very
narrow over most of its length (Figs. 75,
76). But there is considerable variation in
the shape of the posterior median plate
and the shape of its base.
Natural History. A female was collected
in Fspirito Santo in an orb on a shrub in
woods, another in Itabapoana lianging on
a thread from a leaf of a shrub in woods
at night.

one macroseta on one side, fourth with
three short macrosetae, two thick, one thin.
Second and third femora each with a ven-
tral row of macrosetae. Abdomen with 5
tubercles: two anterior, three posterior (Fig,
103). Total length 7.0 mm. Carapace 3.5
mm long, 3.1 wide. First femur 5.2 mm,
patella and tibia 6.0, metatarsus 3,1, tarsus
1.2. Second patella and tibia 4.2 mm, third
2.5, fourth 3.9.
Variation. Total length of females 7.0
to 8.8 mm. The male paratype has only
two macrosetae on the fourth trochanter,
none on the third. The female holotype
and the male paratype collected with it
were illustrated.
Diagnosis. Females differ from those of
P, tarapoa by having a longer scape and
a narrower posterior median plate in the
epigynura (Fig. 98). The male differs from
those of similar species by the nearly round
conductor and shorter median apophysis
(Fig. 102).
Natural History. A male was found in
a rain forest in Rondonia.

beno, 0°07'S, 76°20^W,' Napa Pro v., Ecuador, 23
June to 1 July 1988 (W. Maddison), in MCZ. The
specific name is a noun in apposition after the type
locahty.
Description, Female from Manaus, Bra-
zil. Carapace orange with paired darker
spots. Sternum dusky yellow. Coxae yel-
lowish with dusky marks; legs hght orange
with dusky rings, which are darker on
proximal articles. Dorsum of abdomen with
dark brown median band bordered by
white (Fig, 107); venter black with a pair
of small white spots, spots almost touching
(Fig. 108). Tubercles of lateral eyes small
and indistinct. Posterior median eyes 0.8
diameter of anterior medians, laterals 0.7
diameter. Anterior median eyes their di-
ameter apart. Posterior median eyes slight-
ly more than their diameter apart. Ab-
domen narrow, with five tubercles, and
two pairs of swelhngs on sides (Fig. 107).
Total length 8.0 mm. Carapace 3,4 mm
long, 2,6 wide. First femur 4,0 mm, patella
and tibia 4.8, metatarsus 2.9, tarsus 1,1,
Second patella and tibia 4.0 mm, third 2,5,

Male from Manaus. Color as in female,
except for a transverse white Hne betw een
anterior lateral tubercles on dorsimi of
abdomen. Posterior median eyes 0.7 di-
ameter of anterior medians, laterals 0,6
diameter. Anterior median eves their di-
ameter apart. Posterior median eyes slight-
ly more than their diameter apart. Fourth

pace 3.5 mm long, 2.9 wide. First femur
4.5 mm, patella and tibia 5,2, metatarsus
2.7, tarsus 1 .0. Second patella and tibia 3.6
mm, third 2,1, fourth 3.4.
Note. The male and the female were
collected together in Manaus.
Variation. The holotype is darker than
the specimen described and figured (Fig.
107) and 9.3 mm in total length. All illus-
trations were made from specimens from
Manaus,
Diagnosis. The large, wide median plate
of the epigynum (Fig. 105) separates fe-
males of F. tarapoa from those of F. diviso-
ria, which has a narrower median plate
(Fig. 98). The male is separated by the
wider base of the median apophysis and
the slightly different shape of the embolus
of the palpus (Fig. 109).

the abdomen as long as wide, and lacking
the anterior median tubercle, but having
two posterior median tubercles. Its total
length is 10 mm. The holotype was illus-
trated.

Carapace 3.5 mm long, 2.9 wide. First fe-
mur 3.9 mm, patella and tibia 4.6, meta-
tarsus 2.7, tarsus 1,1. Second patella and
tibia 3.7 mm, third 2,0, fourth 3.2.
Variation, In the paratype both palpal
patellae have one macroseta.
Diagnosis. This male differs from those
of P. monticola, P. divisoria, and P, tomba
by the sculpturing of the base of the me-
dian apophysis and the position of the con-
ductor in the palpus (Fig. 115), and by the
ovoid outline of the abdomen (Fig, 116).

(damaged by insect pin) with trapezoidal,
hghter area, w idest anteriorly; venter dark
with a median light spot. Posterior median
eyes 0.7 diameter of anterior medians; lat-
erals 0,7 diameter. Anterior median eves
0.6 diameter apart. Posterior median eyes
slightly less than their diameter apart.

and tibia 3,2 mm, third 3,1, fourth 4.2.
Note. The male and the female were
not collected together, but they have the
same type locality and distribution.
Variation. Total length of females 12 to
17 mm, of males 7.4 to 8.8. The females
have nine or 10 tubercles on the abdomen:
the last tubercle, the posterior median, may
be missing. The fourth trochanter of the
male from Sirena has two macrosetae on
one side, three on the other. Figures 117-
121 were made from a female from La
Selva, Costa Rica; Fig. 122, from the ho-
lotype of E, arniata.
Diagnosis. Parawixia rigida differs from
other Central American species by having
a median white spot on the venter of the
abdomen {Fig. 121). The female differs
from those of P. hypocrita and P. nesophi-
la, which also have a white spot, by having
the scape of the epigynum long (Figs, 117,
119, 121) and laterally flattened (Fig. 119),
The male differs by the shape of the large
curved median apophysis with a distal
notch (Fig. 122).

and Koch considered the S-mrn-long,
curved scape characteristic of this species:
34 Bulletin Museum of Comparative Zoology, Vol. J 53, No. 1
"zwei Linien langeii, gesclnveift geboge-
nen nadelformigen Legestachel/' Most
other Parawixia species with a long scape
have a more spherical abdomen. Parawix-
ia kochi alhozonata is presumably the same
species as the other two **subspecies'' de-
scribed by di Caporiacco even though the
abdomen is missing. Parawixia kochi mac-
tililatera has the characteristic abdomen
shape and epigynum of P. kochi, Moli-
naranea setosa has the characteristic em-
bolus with a round tip and neck of males
of P. kochi.
Description. Female syntype of E. nii-
nas. Carapace brown, clypeus darkest.
Sternum maculated light and dark brown.
Legs brown, indistinctly ringed. Dorsum
of abdomen shades of brown w ith folium
outHned with dark (Fig, 126); venter brown
with indistinct light patches and some
paired white pigment patches (Fig. 127).
Posterior median eyes 0.8 diameter of an-
terior medians, laterals 0.7 diameter. An-
terior median eyes slightly less than their
diameter apart- Posterior median eyes their
diameter apart. Abdomen longer than
wide, w ith three pairs of lateral tubercles
and five posterior (Fig. 126). Total length
16 mm. Carapace 6.6 mm long, 5.4 wide.
First femur 7.8 mm, patella and tibia 9.5,
metatarsus 6.2, tarsus 2.L Second patella
and tibia 9.2 mm, tliird 5.5, fourth 8.7.
Male syntype of E. niiiias. Carapace or-
ange, less distinctly marked than carapace
of female. Fourth trochanter with one short
macroseta. Abdomen oval, humps indis-
tinct. Total Ic ngth 10,5 mm. Carapace 6,2
mm long, 4,8 wide. First femur 6.9 mm,
patella and tibia 8.4, metatarsus 5.2, tarsus
1.7, Second patella and tibia 6.7 mm, third
4.2, fourth 67.
Variation, Some individuals have a
spherical abdomen, but usually the abdo-
men is longer than wide (Fig. 126), There
alw ays are an anterior pair of tubercles and
five posterior, with two smaller pairs on
the sides. One female from Peru had the
anterior lateral tubercles double. There are
manv individual differences but there is
no consistent geographical variation. How-
ever, there are consistent geographical dif-
ferences in the shape of the terminal
apophysis, embolus, and base of the me-
dian apophysis (Figs. 128-135). Neverthe-
less, in all palpi the tip of the embolus is
round and has a neck, and in all palpi the
base of the median apophysis has a similar
tooth pointing at the radix (Figs. 128-135),
Total length of females 12.8 to 18.8 mm,
of males 8.3 to lO.S. Figures 123 to 128
were prepared from a female from the
Meta Dept., Colombia; Figure 129 was
prepared from a male from Guyana; Fig-
ure 130, from the male syntype of Epeira
tiiinas.
Diagnosis. The female can be recog-
nized by the long, slender scape of the
epigynum with concave sides (Figs. 123-
125), and usually by the slightly elongate
abdomen (Fig, 126). The base of the epigy-
num has two characteristic dark spots (Fig.
123). This is the only Parawixia species in
which the male palpus has a round em-
bolus tip above a neck (Figs. 128-135). The
fourth trochanter of the male almost al-
vvavs has one macroseta; onlv one Peruvian
male lacked the seta.
Natural Hisfrnij. The species has been
collected in its web at night in rain forest,
in secondary forest, savanna, and swamp
fore st, and also on a l)urned out tree. Spec-
imens collected by H. Hofer near Manaus

Note. I follow Key selling in the inter-
pretation of P. atidax, as the species was
not illustrated by Blackwall and Black-
walFs specimens are lost» The immature
specimens of Epeira coronigera have the
abdomen circular, almost as wide as long,
and with a distinct anterior median tu-
bercle as may be characteristic of this spe-
cies. Mello-Leitao's A, riheiroi was perhaps
an immature female of P. audax, having
a soft projection in place of the future scape
of the epigynum. Bad cocks' s immature
specimens of F. eumeniphila have a pair
of white spots on the venter of the abdo-
men as do some immature P. audax and
adult P. undulatci; they may belong to ei-
ther this or the other species. Mello-l.citao
(1942) correctly placed E. audax in Para-
wixia. Bonnet {1956: 1783) erroneously
synonymized the name Epeira duodecim-
tuberculata Bcrtkau with Eriophora so-
cialis [=Parawixia histriatal
Description. Female from Pinhal, Santa
Catarina, Brazil. Carapace orange with
white hair and a few dark hairs; elypeus
brown. Sternum, coxae orange; legs orange
with dark spots. Dorsum of abdomen yel-
lowish with brown marks (Fig, 139); ven-
ter dusky with three pairs of small white
spots and a white streak on each side (Fig.
140). Cephalic area of carapace with a pair
of swellings. Posterior median eyes 0.9 di-
ameter of anterior medians, anterior lat-
erals 0.9 diameter, posterior laterals 0.8
diameter. Anterior median eyes slightly
more than their diameter apart. Posterior
median eyes their diameter apart- Abdo-
men with 13 tubercles: one anterior me-
dian, four pairs on sides and four posterior
(Fig. 139). Total length 12.0 mm. Cara-
pace 5.6 mm long, 4.5 wide. First femur
5.4 mm, patella and tibia 7.2, metatarsus
4,5, tarsus 1.7, Second patella and tibia 6.0
mm, third 3.5, fourth 5/4,
Male from PinhaK Santa Catarina, Bra-
zil. Color as in female. Posterior median
eyes 0.8 diameter of anterior medians, lat-
erals 0,5 diameter. Anterior median eyes
their diameter apart. Posterior median eyes
their diameter apart. Lateral eyes 0.6 di-
ameter apart. Fourth trochanter without
macroseta. Second and third femora with
ventral row of strong macrosetae, first and
fourth with two rows. Abdomen \^ ith 13
tubercles as in female. Total length 8,4
mm. Carapace 4.1 mm long, 3.7 wide. First
femur 4,1 mm, patella and tibia 5.6, meta-
tarsus 3.3j tarsus 1.3. Second patella and
tibia 4.5 mm, third 2.5, fourth 3.7.
Variation, The anterior, median tuber-
cle of the abdomen is frequently missing.
Some females have the anterior lateral tu-
bercles double. The photograph of a fe-
male from S of Jujuy, Argentina, shows
her to be mostly green and white with
some brown spots and brown patellae
matching the lichens of the substrate. Im-
matures may have a pair of white patches
on the venter of the abdomen. Total length
of females 10,0 to 20.8 mm; of males 7.7
to 9.6, Figures 136-139 were made from
specimens from Canela, Rio Grande do
Sul, Brazil; Figures 140-142, from Pinhal,
Santa Catarina, Brazil.
Diagnosis. Females differ from those of
P. bistriata by having distinct tubercles on
the abdomen (Fig. 139), from those of F.
undulata by having the posterior median
plate of the epigynum swollen, sclerotized,
and dark in color (Fig, 137), and from
those of both by the pattern on the venter
38 Bulletin Museum of Comparative Zoology, Vol 153, No. 1
of the abdomen (Fig. 140), Males differ
from most species of Parawixia by lacking
macrosetae on the fourth trochanter, from
P. bistriata by having tubercles on the ab-
domen, and from both P. bistriata and P.
tindiilata by the shape of the base of the
median apophysis and the shape of the
terminal apophysis of the palpus (Figs. 141,
142).
Natural History. This is perhaps the most
common araneid orb weaver in southern
Brazil. I made the following notes on 22
March 1985 at Cataratas do Iguagu, Brazil.
This Parawixia is very common and makes
an enormous web, with a bridge about 2
m long, the web 50 to 90 cm in horizontal
diameter, with very loose, w ide mesh (Plate
1). The bottom of the orb is about 1 to 2
m above the ground. The spider hangs in
the middle, cephalic region down (Plate
1), or hides in a silk retreat within a curled
leaf near a radius or a frame line. The
spider walks to the retreat when disturbed
and if touched tliere, drops slowly on a
thick silk rope. If handled the female tries
to throw silk on the hand. 1 watched in-
dividuals feed on grasshoppers 3.5 cm long,
longer than the spider. The viscous silk is
very sticky. No two specimens have the
same dorsal coloration of the abdomen or
similar humps; the reddish and green col-
oration of some individuals is w ashed out
in alcohol. The spider is probably mostly
nocturnal and builds at night.
Distribution. Amazon area to Chubut
Province, Argentina (Map 3).

Diagnosis. Females differ from those of
P. histriata by having tubercles on the ab-
domen {Fig. 146), from those of F. audax
by having the posterior median plate of
the epigynum not selerotized, flat, and
usually white (Fig. 144), The venter of the
abdomen, unhke that of P, histriata and
of adult P. audax, has a pair of white
patches on black (Fig. 147). Males differ
from those of P\ histriata by having tu-
bercles on the abdomen and from males
of P. bisiriata and P, audax by the shape
of the terminal apophysis and the proximal
end of the median apophvsis (Figs. 148,
).
Natural History, One female from Sao
Paulo State came from a shrub in a field
along the road; the web was 40 cm in di-
ameter.

Note. Rengger gave the name ^^ Epeira
histriata oder [or] socialis' ' to this species.
Epeira bistriata has never been illustrated
before. According to Rengger its main
characters are that it is a "social Epeira
with a hazelnut-shaped abdomen having
red spots." Only one species fits this de-
scription, the one illustrated here. Reng-
ger's specimens are not in NHMB or in
the Naturmuseum Aarau, Switzerland (R.
Maurer, C. Stocker, personal communi-
cation).
42 Bulletin Museum of Comparative Zoology, Vol 153, No. 1
C. L. Koch's Epeira hicolor (Fabricius)
is a large spider from BraziL Critical fea-
tures are a spherical abdomen with trans-
verse marks, no distinct marks on the un-
derside of the abdomen and a S-mm-long
scape C'2 Linien langen, uber dieselbe
ruck warts gebogenen Legstacher). This
fits Farawixia bistriata. But this is proba-
bly a misidentification of Aranea hicolor
Fabricius (1798: 230), which has a worth-
less, unrecognizable description of a spider
from "America." Aranea hicolor Fabricius
(1798) is also a junior homonym of Ara-
nea hicolor Olivier (1789: 230). Olivier 's
Aranea hicolor is a worthless description
without a holotype for a spider from Gua-
deloupe, Lesser Antilles (see also Petrunke-
vitch, 1911).
Holmberg (1874) writes that the scape
of E. burmeisteri reaches the center of the
spinnerets. This is characteristic for this
species, but not known for any others. Me-
Ilo-Leitao (1932) thought Burmcistrr'sand
Holm berg's descriptions fit a diiierent so-
cial species, common in Argentina. This
could not be verified.
The spider is known in Spanish as the
*'nanduti'' spider, derived from the word
for "spider-web" in the Guarani language
(Fowler and DiehL 1978; Kochalka, 1989,
personal communication), in Portuguese as
aranJia do cerrado (C. Sandoval, 1990,
personal communication).

Variation. Total length of females 16.7
to 27 mm, of males 1 1.7 to 18.5. In adult
females preserved in alcohol the abdomen
is variable in color. In immature specimens
the abdomen has a diagnostic pattern and
three to four pairs of lateral tubercles, and
two posterior, median tubercles {Fig, 157).
The tubercles may be visible on the ab*
do men of males. Early in stars are almost
all black; later instars have light stripes, a
longitudinal row of dark red dots on the
tubercles on each side, and a faint red spot
in the cardiac area. Adults are mostly dark
gray with a little red anterior lateral on
the abdomen dorsum (Kochalka, 1989,
personal communication; and color pho-
tographs by C. P. Sandoval, Plate 1). Fig-
ures 150, 151 were prepared from the ho-
lotype of £. aeronavis. Figure 152 was
made from a female from Tucuman, Ar-
gentina, 153-155 were made from syn-
types of A. nordenskioldi^ and 157 was
prepared from an immature from Barra
da Tapirape, Ma to Grosso, Brazil.
Diagnosis. Females differ from those of
P. audax and P. undulata by having a
spherical abdomen sometimes with only
three faint pairs of lateral tubercles, in-
distinctly marked on the venter (Figs. 153,
154). The scape of the epigynum is less
sclerotized than in P. audax and P. un-
dtdata and the posterior median plate may
be white (Fig. 151). Males differ from those
Parawima •Levi
43
of the similar two species by having a prox-
imal constriction of the median apophysis,
and l>\ the shapes of the base of the median
apophysis and the distal end of the ter-
minal apophysis (Figs. 155. 156),
Natural History, The species has com-
mnnal webs 2 to 5 m above the ground,
just beyond reach, often on telephone poles
in urban and suburban areas, in open
woodland and orchard, in the lower Pan-
tanal, and in isolated trees in drv areas,
but never in a forest having a closed can-
opy- Individuals cluster during daytime in
a common shaded retreat ''as big as a hat,"
constructed with relatively little silk (Plate
1). At dusk the spiders move out on thick
silk lines that stretch as far as 30 m and
build orbs. Within an hour all orbs are
completed, and may cover a 100 m- area.
The orbs are taken down at daw n. Marked
spiders do not return to the same spot as
that of the previous night, but build in the
vicinity. Large prey ensnared are over-
powered and fed on by many spiders, the
number in proportion to prey size. Repro-
ductive casts of ants are a common prey
item, but are not the onlv food. All spiders
in a colony are of the same age and molt
during the same week. Spiders transferred
to another colony are not attacked and
neighboring colonies may fuse. Males and
females mature in late January in southern
Brazil The number of males is approxi-
mately equal to that of females. Following
the final molt, females disperse and deposit
egg'Sacs w ith a mean of 551 eggs, less than
half the number laid bv related araneids
of equal size. Spiderlings emerge in May.
In the laboratory there are eight postem-
l)ryonie ins tars. (J. Koch a Ik a, C, Sandoval,
personal communications; Fowler and
Diehl, 1978; Fowler and Gobbi, 1988a,b).
Rengger gives colony size as between 30
to 40 individuals; Azara in 1808 estimated
less than 100 individuals (Fow ler and Diehl,
1978; Kochalka, 1989, personal commu-
nication). In 1965, when visiting Rio de
Janeiro, I saw what 1 believed to be webs
of this species, high up on telegraph poles
outside the entrance of the Parque da Ci-
dade. too high up to collect, I could not
find any webs on a return visit to the same
spot in 1987. Carter (1928) claims that the
spiders' bite is venomous. They can kill
beetles larger than 2.5 cm in a few minutes
and thert^ are records of birds trapped in
their webs (C. Sandoval, personal com-
mLinication).
Venom. The Hospital Vital Brazil of the
Institute Butantan has recorded only three
accidents, all of persons living in the area
surrounding the city of Sao Paulo: In 1964,
a 7-year-old girl was bitten on the hand
with only slight pain. In 1966, an 18~year-
old man was bitten on the foot; no treat-
ment was necessary. In 1970, a baby of
eight months was bitten on the buttock
w ith moderate local pain, edema and mild
erythema. In all cases punctures of fangs
w ere visible. The first and last victims were
treated with antihistamines and analgesics.
Vellard, in his book on spider venoms
(1936: 262), did not cite anv accidents with
the species, but expressed the belief that
they do occur and are not serious. In recent
years, V. P. D, von Eickstedt has received,
from the Sao Paulo State Central Electrical
Co. from Andradina and from Pirassunun-
ga, requests for help in removing the spi-
ders because workers were afraid to work
on poles with webs (Vera 1\ D. von Eick-
stedt, 1990, personal correspondence).
